Product details

The Siemens SENTRON 5SN6350-7CN is a 3-pole miniature circuit breaker (MCB) rated 50 A with a C tripping characteristic, designed for 400 V AC systems at 50/60 Hz. The IP20 enclosure (with connected conductors) is standard for enclosed distribution boards.

Integration and installation notes

The 5SN6350-7CN accepts solid conductors up to 25 mm², and its 70 mm installation depth fits standard distribution board depths. It is sealable and halogen-free/silicon-free — relevant for environments where outgassing or contamination is a concern. The design supports bolt-on auxiliary devices (shunt trip, alarm switch, auxiliary contact) for remote signaling or emergency-off integration.

The neutral conductor is not switched by this breaker (3-pole, solid neutral). Touch protection (finger-safe terminals) is standard.

Frequently asked questions

What are the key ratings of the 5SN6350-7CN?

It is a 3-pole, 50 A, C-curve MCB rated 400 V AC, with a 6 kA breaking capacity per EN 60898. Operating frequency is 50/60 Hz.

Will the 5SN6350-7CN fit in a panel designed for the 5SL4363-7?

Yes, both share the same footprint: 76 mm depth, 54 mm width (3 modular units), 90 mm height, and 70 mm installation depth. The 5SN6350-7CN is a direct mechanical fit for the same DIN-rail position.

Where can I buy the 5SN6350-7CN?

It is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commercial response.
